My dw is a math teacher with over 15 years professional experience. Despite the much touted and oft moaned about shortage of math teachers, she couldn't get a teaching job for nearly a year after our son was born (she didn't go back to work until he was two..very cool). She eventually got a math position at a private school and she took it. It was her only offer.
What did she discover during her job search process? If you have experience you're a cost-prohibitive hire
... it's not that there's a teacher shortage, it's that there's a funding shortage which makes experienced teachers too expensive. However, if you're in college or just out of college, you can get an emergency credential (dw couldn't get one despite 3 months of begging) and a job lickety split. Of course, that's because the districts don't have to pay you anything above poverty so you're a cost-friendly hire
A thing about credentials... does a course in the US Constitution (which involves the mere memorization of verses and patriotic mythology), a course in chocolate as a drug, and four semesters of "student teaching" (for a professional with 15+ years experience?! why?) really mean a teacher is qualified to teach? We are a culture obsessed with pieces of paper instead of the substantive expertise those papers purport to signify. Experience allegedly used to count. Now it's just an economic barrier. That a school can't find a teacher for their math course is not only immoral and stupid, it's an act of sabotage against our kids because it's a myth... it's that they don't want to pay for good teachers, not that there aren't any around.
When teachers are treated like the professionals most of them actually are, are paid accordingly, the districts funded accordingly, then all the rhetoric about shortages, "education Residents"... I mean "Presidents"... will actually be meaningful. When "credentials" actually mean something real, and professional field experience is seen as economically desirable instead of too-expensive, then we won't have idiotic and baseless problems that shortchange our kids and sabotage the future. It's always curious to me that my wife is paid barely enough to live (for only 10 months a year, the other two we're on our own) while the principal of our dd's public school makes enough to drive a Lexus and take 8 weeks of paid vacation a year. Can we say misdirection of funds? And then there are the parents who say teachers are overpaid?! Another hole for my anger to spill into....
Okay, off my soapbox rant. I get so steamed about this issue because we live it at home.
